Protective device for punch

Abstract

The invention provides a protective device for a punch and relates to the technical field of punch protection. The protective device for the punch comprises a punching machine tool. A workbench is arranged in the center of the punching machine tool. A power device is arranged at the top of the punching machine tool. A punching rod is arranged at the bottom of the power device. A punching block isfixedly connected to the bottom of the punching rod. A reset mechanism is arranged at the front end of the top of the workbench. A separation mechanism is slidably connected to the center of the resetmechanism. A buffer mechanism is arranged at the bottom of the separation mechanism. A sponge block is arranged at the bottom of the buffer mechanism. The simply designed mechanical protective deviceis used and is matched with an optical grating protective device, thus double protective effects can be achieved, under the circumstance of a failure of an optoelectronic device, a very good protective effect can still be achieved on workers through the mechanical protective device, work efficiency is improved greatly, and meanwhile risk cost of the workers and a manufacturer is also lowered greatly.

Description

technical field [0001] The invention relates to the technical field of punching machine protection, in particular to a protection device for a punching machine. Background technique [0002] The stamping machine drives the flywheel through the motor, and drives the crank linkage mechanism through the clutch and the transmission gear to move the slider up and down, and drives the drawing die to form the steel plate. The flywheel drives the gear, crankshaft (or eccentric gear), connecting rod, etc. to run through the clutch to achieve the linear motion of the slider, and the movement from the main motor to the connecting rod is a circular motion. [0003] The main function of the punching machine is to stamp the sheet metal. Every time the punching machine is punching, there are great safety hazards. When the worker finds that the position of the workpiece to be processed is shifted on the punching machine, he will subconsciously Use your hands to straighten it. Once the work...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a protection device for a punching machine, which solves the problem that there is a great potential safety hazard in each punching process of the punching machine. When shifting, they will subconsciously use their hands to straighten it. Once the worker puts his hand into the center of the punch press, the finger will be severed, and the entire finger will be cut off. In addition, the punch sometimes has workpiece positioning errors, and the workpiece is removed from the punch during processing. In the case of being jumped out, thereby injuring the workers, causing serious consequences
